从科学技术哲学角度看金属固态相变

Understanding metal solid state phase by science technic philosophy

应用科学技术哲学的观点综合阐述了金属及合金固态相变理论中的有关问题.认为,金属及合金。

Some questions of metal and alloy solid state phase were talked about by science technic philosophy view.It is blieved that not only metal and alloy but also steel and alloy steel are complicated conformity system.They are composed of a series of subsystems and have some characteristics and functions such as 'whole bigger than part'and so on.Phase has self-organising mechanism.And phase is a kind of evolvement from quantitative change to qualitative change with transition and phase characteristic.Super-cooling austenite should be looked as a subsystem and the whole process of pearlite-bainite-martensite change should be studied by means of system conformity.Science notion is the cell of theory,and some error notions about phase theory in the steels were modified.
