	Pearlite microstructure under increasing surface strain  This is a clip of my work during my 50 days internship at Newcastle university. It just shows the gist of what the actual code can do. The quality of colors is slightly poor, can't help it. 2010年08月14日再生回数 1053

	Steel Heat Treatment: "Elements of Tempering, Normalizing, and Annealing" 1945 14min  more at scitech.quickfound.net "Explains how steel is tempered, how the structure, toughness, and hardness of plain carbon steel changes at progressive tempering stages, and how steel is normalized and annealed. Describes the results." Public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization (the resulting sound, though not perfect, is far less noisy than the original). en.wikipedia.org The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance. Note that the electrical and thermal conductivity are slightly altered. As with most strengthening techniques for steel, Young's modulus is unaffected. Steel has a higher solid solubility for carbon in the austenite phase; therefore all heat treatments, except spheroidizing and process annealing, start by heating to an austenitic phase. The rate at which the steel is cooled through the eutectoid reaction affects the rate at which carbon diffuses out of austenite. Generally speaking, cooling swiftly will give a finer pearlite (until the martensite critical temperature is reached) and cooling slowly will give a coarser pearlite. Cooling a hypoeutectoid (less than 0.77 wt% C) steel results in a pearlitic structure with α ... 2012年03月02日再生回数 1710

	Metals and Alloys, lecture 10, Alloys of Iron  The development of improved metallic materials is a vital activity at the leading edge of science and technology. Metals offer unrivalled combinations of properties and reliability at a cost which is affordable. They are versatile because subtle changes in their microstructure can cause dramatic variations in their properties. For example, it is possible to buy commercial steel with a strength as low as 50 MPa or as high as 5500 MPa. They can be made with a microstructure which is finer than that of carbon nanotubes. An understanding of the development of microstructure in metals, rooted in thermodynamics, crystallography and kinetic phenomena is essential for the materials scientist. The majority of the 1.4 billion tonnes of metals produced annually are the result of developments within the last ten years www.msm.cam.ac.uk 2011年04月24日再生回数 2814
	Phase Percentage and Carbon Content Estimation in Hypoeutectoid Steels by Image Processing  demonstrations.wolfram.com The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. This Demonstration shows that performing image processing with Mathematica is not just easy, but extremely useful. In this case, we analyze the microstructure of two methallographic samples of hypoeutectoid steel, extracting the percentage of pearlite v... Contributed by: Jorge Garcia Tiscar 2010年04月20日再生回数 1562
	Pro-Mix BX Soil Organic Growing Advantages  Darren from the Grow Show in Ann Arbor Michigan explains differences and uses of Pro-Mix soil mixes. Hi, I'm Darren at the Grow Show in Ann, Arbor, Michigan. We're talking about Pro-Mix industrial soilless medium. It contains primarily Sphagnum peat moss. The Grow Show carries both Pro-Mix BX & HP. Pro-mix HP with pearlite for drainage and aeration, dolomitic lime for ph balance and a wetting agent. Pro-Mix BX retains a bit more water so it contains more peat moss, added vermiculite with the lime & pearlite. Both contain microrise - specifically endomicrorise. Pro-Mix BX with fungicide contains bacillus subtilis and it fights root rot and root diseases. All this is available at the Grow Show in Ann Arbor, Michigan or online at www.thegrowshow.org. 2011年11月29日再生回数 1979
	Square Foot Garden in Branson, MO  Here's a short overview of our square foot gardens at our house in Branson, MO. There's a book you can buy about this concept of gardening, but there are some options on how you want to do it exactly. We're using strictly store bought 'soil' mixture, which is basically various types of compost, manure, peat moss, organic soil mixes, and most importantly use the vermiculite instead of pearlite. I hope my spelling is correct, but they say the pearlite will float to the surface over time, and you don't want that. We're also composting our own food and yard wastes and add that to our mix. 2011年04月07日再生回数 103
	Rocket stove,Bushcraft, easiest build ever 2 one gallon paint cans.  Build one of these stoves I guarantee you will not be dissapointed it was the easiest build ever and works perfectly. It took me a while because I really didn't know what I was going to have when I was finished now that I have built one I bet I could build one in about 5 min if I had all supplies ready. I just might do that set up a cam and do a build under 5 min. 2 Paint Can Rocket Stove. Supplies are 2 one gallon paint cans ,one lid, one 4" 90 ~$4 degree elbow, one 4" metal tube~$4,bag of pearlite under $4, l purchased @ LOWES. Add them up and cost under $15 lowes. This thing fired right up I crumpled up some paper and tossed them in the top then lit a stick and inserted in the feed tube. I spent the night enjoying my new stove I might tap some holes in the base JIC it gets water in it so it will drain. Not too big don't want to loose any pearlite. Fashion some tin to split the feed tube to allow proper air fuel mixture. This thing burns real hot even with the pearlite it is too hot to touch but you can move it with caution, a stick and the little handle already on the can. I thik I will first use it to kill the fire ants in the yard I was told that If you pour boiling water on them they will expire and you are not risking poisoning any useful insects. I have to get another can to build a second stove. I was going to use a 5 gallon paint can but it really would not make any sense to me to have that much space to fill with pearlite besides these little cans were easier ... 2010年03月28日再生回数 4172
