quenched martensite

The large welding current caused the formation of quenched martensite and the high residual stresses in the welding zone, resulting in the increase of zinc sensitivity of hydrogen attack.

结果表明：由于焊接电流过大，使焊缝产生淬火马氏体组织及较大的焊接残余应力，导致镀锌氢脆敏感性增加，造成吸油盘发生氢脆开裂。

While the bearing roller is quenched into UNCON ( 15w%) or water, it can get a lot of martensite. At the same time, the hardness and quenching layer of bearing roller meets the needs, but the residual stress is larger.

以UNCON（15%）或水为淬火介质时，可以得到大量的马氏体，支承辊硬度和淬硬层深也符合要求，但残余应力较大。
