求翻译：热处理后合金的矫顽力、剩磁和饱和磁化强度随热处理温度有所波动，其中840℃淬火合金具有较小的矫顽力和大的饱和磁化强度。是什么意思？

After heat treatment the alloy coercivity, remanence and saturation magnetization with the annealing temperature to fluctuate, including 840 ° C quenched alloys with smaller coercivity and saturation magnetization.

Heat-treated alloy after the coercivity, residual and saturation magnetization with the heat treatment temperature fluctuations, which 840 °C hardened alloy has a small coercivity and the saturation magnetization.

After the heat treatment the alloy coercive force, the residual magnetism and the saturatio magnetization has the undulation along with the heat treatment temperature, in which 840℃ quenches the alloy to have the small coercive force and the big saturatio magnetization.

Alloy after heat treatment of the coercivity, residual magnetism saturation magnetization and heat treatment temperature fluctuates, of which 840 ℃ tempered alloy with low coercivity and large saturation magnetization.
