硬度单位的转换度換算公式:1、肖氏硬度(HS)=勃式硬度(BHN)/10+122、肖式硬度(HS)=洛式硬度(HRC)+153、勃式硬度(BHN)= 洛克式硬度(HV)4、洛式硬度(HRC)= 勃式硬度(BHN)/10-3硬度測定範圍:HS<100 HB<500 HRC<70 HV<1300(80~88) HRA,(85~95) HRB,(20~70)HRC洛氏硬度中HRA、HRB、HRC等中的A、B、C为三种不同的标准,称为标尺A、标尺B、标尺C。
洛氏硬度试验是现今所使用的几种普通压痕硬度试验之一,三种标尺的初始压力均为98.07N(合10kgf),最后根据压痕深度计算硬度值。
标尺A使用的是球锥菱形压头,然后加压至588.4N(合60kgf);标尺B使用的是直径为1.588mm(1/16英寸)的钢球作为压头,然后加压至980.7N(合100kgf);而标尺C使用与标尺A相同的球锥菱形作为压头,但加压后的力是1471N(合150kgf)。
因此标尺B适用相对较软的材料,而标尺C适用较硬的材料。
实践证明,金属材料的各种硬度值之间,硬度值与强度值之间具有近似的相应关系。
因为硬度值是由起始塑性变形抗力和继续塑性变形抗力决定的,材料的强度越高,塑性变形抗力越高,硬度值也就越高。
但各种材料的换算关系并不一致。
本站《硬度对照表》一文对钢的不同硬度值的换算给出了表格,请查阅。
硬度表示材料抵抗硬物体压入其表面的能力。
它是金属材料的重要性能指标之一。
一般硬度越高,耐磨性越好。
常用的硬度指标有布氏硬度、洛氏硬度和维氏硬度。
1、布氏硬度(HB) 以一定的载荷(一般3000kg)把一定大小(直径一般为10mm)的淬硬钢球压入材料表面,保持一段时间,去载后,负荷与其压痕面积之比值,即为布氏硬度值(HB),单位为公斤力/mm2 (N/mm2)。
2、洛氏硬度(HR) 当HB>450或者试样过小时,不能采用布氏硬度试验而改用洛氏硬度计量。
