The result indicated that crack was caused by lath-shape inclusion in the material and highquenching rate.
结果表明,由于材料中存在长条状夹杂物及淬火冷却速度过快导致螺母开裂。

Highquenching rate which can be obtained by the rational combination of quenching parameters mentioned above is the key to gain noncrystalline structure and high quality amorphous strips.
液淬工艺参数的合理配合下获得的足够高的液淬速率是得到非晶结构的关键,也是制备质量条带的决定因素。

Employing abrasive machining for the form of the gear and intellective-control carburizing and quenching technology for the surface, the gear is with high intensity, strong tenacity and wearability.
