>> Basci definitions and concepts:

>> The martensitic transformation
		The martensite term indicates at the beginning the component of hardening in steels. It comes from the eminent German metallurgist Adolf Martens. If steel undergoes a hardening starting from the high temperature phase named austenite, this one sees its hardness increase...
>> The diagram of state
		Shape memory alloys have a different behavior from usual materials. A material with shape memory is characterized mainly by a diagram of state Stress-Temperature...
>> Polycrystalline and monocristalline alloys
		From the microstructural point of view, the behavior is different according to crystallographic nature from the sample...
