布氏硬度计

CHANPINSHIJIAN:2019-11-05

JIANYAOMIAOSHU:

布氏硬度计是测量金属布氏硬度的精密计量仪器 。
主要用于铸铁、钢材、有色金属及软合金等材料的硬度测定,布氏硬度试验是所有硬度试验中压痕大的一种试验法,它能反映出材料的综合性能,不受试样组织显微偏析及成分不均匀的影响,精度较高。

布氏硬度试验的优点是硬度代表性好,布氏硬度试验一般采用的硬质合金球压头直径比较大试验力可以高达3000kg,其压痕面积比较大,能排除金属材料微小池同内组成相的差异影响,全面反映出多晶体的金属材料的综合 能的平均值,因此特别适用于灰铸铁、退火钢,轴承合金等晶粒粗大的金属材料的测定,试验数据重复性好,结果也稳定。并且研究表明佰氏硬度值 抗拉强度值之间存在较好的对应关系
