45A钢卡爪淬火开裂原因分析

We need an extra $ 45a week .

我们每周需要多花45美金。

It is introduced the development of 45A narrow strip and introduced the influence on the production performance by the deformation and the strength of cooling by CCT curve .

阐述45优质窄带钢的开发，结合CCT曲线介绍轧制变形量、冷却强度对产品性能的影响。

Without welding wire , the joint strength is about 79 percent of the base material at 45A welding current . The joints strength is increased with welding wire .

不使用填充焊丝，当焊接电流为45A、钨针直径为1.6mm、保护气体流量为15L/min时，AZ31镁合金薄板氩弧焊接头的力学性能可达到母材的79%左右。

When arc current value is 45A , the optimum negative bias voltage is - 175V , SP3 bonds in the film is 49.86 % ;

采用VAC法入射粒子的能量和入射粒子的密度都存在一个阈值，当弧流为45A时，最佳负偏压值为-175V，此时DLC膜中最高SP~3键含量为49.86%；

Dunne , 45a native New Yorker transplanted to Texas when he was17 , is quick to point out that luxury loos are not his only businese .

唐恩这位45岁土生土长的纽约人，17岁时移民德克萨斯。他明确地指出：他不只是经营“豪华厕所”的生意。

It was found that , at 40 A and 45A welding currents , the tensile strength of the welded joints got to 205 MPa , which was about 80 % of the parent materials , and that tensile samples always fractured at heat affected zones .

结果发现：焊接电流为40A和45A时，焊接接头的力学性能最好，（σb为205MPa），为母材强度的80%左右，断裂总是发生在热影响区。
