  If creep is considered a high temperature phenomenon, how is it a factor of glacier movement?

  In martensitic transformation the amount transformed is dependent only on temp not on time

  1. Advantage of TTT diagram over Iron-Iron carbon diagram - Has time axis 2. Disadvantage of TTT diagram over Iron carbon diagram - TTT diagram for only single composition

  Why coarse grain in annealing and fine grain in normalising 19:20 -Annealing occurs at higher range of temperature and Tempering occurs at lower range of temperature. - At higher temperature I. E. Annealing - growth rate dominate nucleation, so coarse pearlite are formed - At lower temperature I. E. Normalising - nucleation dominate growth rate, so more nucleation occurs than growth, so fine pearlite formed.

  Why C curve? 11:12 to 12:57 -Initially (near TE) Driving force is less but atomic mobilisation is high -Finally (near T=0C) Driving force is high but atomic mobilisation is very less

  how can liquid exist below its freezing temperature i mean by that time everything would have been converted solid itself right how will nucleation occur below Tm as what i understood was freezing will occur till complete liquid changes to solid and until then T will remain constant at Tm

  @24:72 this fraction is valid only at that particular temperature right .i.e, the lever should be made corresponding to the equilibrium temperature in question right?

  Спасибо. Очень наглядно и понятно. Один только вопрос - если в роли матрицы будет выступать композитный полимер, выплавленный из LFT-G -гранул (композитные гранулы с длинными волокнами углерода/базальта/стекла), а в него будет добавляться керамический нано-аддитив по типу нитридных или карбидных нановискеров, то это будет гибридный нанокомпозит с несколькими фазами (нано- и макро-фазы)?? Или же это будет полимерно-волоконно-керамический нанокомпозит, как пример GFRP-LFT-G-nSi3N4 (матрица - сплавление в лист гранул LFT-G TPU/RTPU + LGF, а добавляемый наноаддитив - нановискеры нитрида кремния)?

  Sir, why volume constancy is valid in plastic deformation ?

• 
  @introductiontomaterialsscienceАй бұрын

  This is good question. I think we can say that this is an experimental observation. The atomic mechanisms of plastic deformation are consistent with this fact. So in slip one part of the crystal slides over the other part and so the volume remains constant. In twinning, the crystal reorients itself, again keeping the volume constant.

  I have made two mistakes in this video : 1. I have considered Trigonal and Rhombohedral as synonyms for the same crystal system. However, as per the International Tables of Crystallography Vol A it.iucr.org/A/ the two terms are NOT synonymous. Crystal System should only be called Trigonal and not Rhombohedral. 2. I have shown only one Bravais lattice in the trigonal crystal system. But in reality there are two Bravais lattices in the trigonal system: hexagonal prinmitive (hP) and hexagonal rhombohedral (hR). And so there is no trigonal P Bravais lattice as shown in the table in this video. I plan to make a video to clarify this. Wil share the link once I do it. You can check en.wikipedia.org/wiki/Crystal_system.

  Sir In the entire Strength of materials we study is Engineering stress or True Stress or both?

• 
  @introductiontomaterialsscienceАй бұрын

  In the strength of materials we usually confine ourselves to elastic regime. In the small strains corresponding to elasticity there is not much difference between true and engineering stress. The difference becomes significant only when the strains are large, like in plastic deformation.
