Made by mixing elemental or alloy powders and compacting the mixture in a die, the resultant shapes are then sintered or heated in a controlled atmosphere furnace.
通过混合元素或合金粉末并在模具中压实混合物，再烧结或在环境可控炉内加热制成最终形状。

The SM master alloy was used to add high oxygen affinity elements Mn and si into the sintered steel as alloying elements to improve the mechanical properties.
通过添加硅锰母合金，将硅、锰这两种对氧亲和力较高的元素加入到烧结钢中，以改善烧结钢的力学性能。

But the addition of SM master alloy has some deleterious effect on the toughness of sintered steel.
