In this work the influence of various plasticizers on sintering powder materials based upon iron alloyed with copper is studied. It is shown that introduction of plastifiers into powder mixtures increases relative density by 4–10%. Performance of thermal mixing has a favorable effect on relative density after sintering. A workpiece after sintering with “warm” mixing has a relative density of 90–94%. The greatest relative volumetric shrinkage of 6.5% is observed for specimens of the composition PZhRV 2.200.28 + 0.7 wt.% Br + 0.7 wt.% Cu + 1 w t.% s t. C u + 1 wt.% Al₂O₃ mixed in a paddle mixer in a warm regime. Shrinkage is almost absent in specimens of composition PZHRV 2.200.28 + 0.7 wt.% Br + 0.7 wt.% Cu + 1 wt.% st. Cu.

在这项工作中，研究了各种增塑剂对基于铁铜合金的烧结粉末材料的影响。结果表明，在粉末混合物中引入增塑剂可使相对密度增加 4-10%。热混合的性能对烧结后的相对密度有有利的影响。“温”混合烧结后的工件的相对密度为 90-94%。对于组合物 PZhRV 2.200.28 + 0.7 wt.% Br + 0.7 wt.% Cu + 1 wt.% s t 的样品观察到最大相对体积收缩率为 6.5%。Cu + 1 wt.% Al ₂ O ₃在桨式混合器中以温热状态混合。PZHRV 2.200.28 + 0.7 wt.% Br + 0.7 wt.% Cu + 1 wt.% st. 组成的样品几乎不存在收缩。铜。
