19、度其值表示材料外表抵抗坚硬物体压入的能力。最流行的里氏硬度HL、肖氏硬度(HS)则属于回跳法硬度试验，其值代表金属弹性变形功的大小。因此，硬度不是一个单纯的物理量，而是反映材料的弹性、塑性、强度和韧性等的一种综合性能指标。1、钢材的硬度 ：金属硬度(Hardness)的代号为H。按硬度试验方法的不同，常规表示有布氏HB、洛氏HRC、维氏HV、里氏HL硬度等，其中以HB及HRC较为常用。 HB应用围较广，HRC适用于外表高硬度材料，如热处理硬度等。两者区别在于硬度计之测头不同，布氏硬度计之测头为钢球，而洛氏硬度计之测头为金刚石。 HV-适用于显微镜分析。维氏硬度(HV) 以120kg以

20、的载荷和顶角为136°的金刚石方形锥压入器压入材料外表，用材料压痕凹坑的外表积除以载荷值，即为维氏硬度值(HV)。 HL手提式硬度计，测量方便，利用冲击球头冲击硬度外表后，产生弹跳；利用冲头在距试样外表1mm处的回弹速度与冲击速度的比值计算硬度，公式：里氏硬度HL=1000×VB回弹速度/ VA冲击速度。目前最常用的便携式里氏硬度计用里氏HL测量后可以转化为：布氏HB、洛氏HRC、维氏HV、肖氏HS硬度。或用里氏原理直接用布氏HB、洛氏HRC、维氏HV、里氏HL、肖氏HS测量硬度值。时代公司生产的TH系列里氏硬度计就有此功能，是传统台式硬度机的有益补充！详细情况请点击?里氏

21、硬度计TH140/TH160/HLN-11A/HS141便携式系列 ?洛氏硬度(HRC)一般用于硬度较高的材料，如热处理后的硬度等等。2、HB - 布氏硬度：一般用于材料较软的时候，如有色金属、热处理之前或退火后的钢铁。布式硬度(HB)是以一定大小的试验载荷，将一定直径的淬硬钢球或硬质合金球压入被测金属外表，保持规定时间，然后卸荷，测量被测外表压痕直径。布式硬度 值是载荷除以压痕球形外表积所得的商。一般为：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外表，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/m

22、m2)。 关于布式硬度(HB)详细情况请点击?布氏硬度机(计)HB-3000B/TH600 ?3、洛式硬度是以压痕塑性变形深度来确定硬度值指标。以0.002毫米作为一个硬度单位。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。它是用一个顶角120°的金刚石圆锥体或直径为1.59、3.18mm的钢球，在一定载荷下压入被测材料外表，由压痕的深度求出材料的硬度。根据试验材料硬度的不同，分三种不同的标度来表示：                               &
