A class degenerate quasilinear parabolic systems is considered. The local existence is proved. In some conditions the solution quench in a finite time. And an estimate of quenchingtime is given.
The result indicates that under different quenching temperature and holding time, the formed bainite morphology are different.
结果表明，在不同淬火温度和保温时间下形成不同的贝氏体形貌。

The effect of quenching temperature, the interval time from quenching to aging and aging institution to 2A70 aluminium alloy pre-stretching plate structure and properties are introduced.
