※ 引述《skyno321 (三媽)》之銘言：
: 請問一下板上的大大
: 維克式(HV)要用什麼公式 可以算成 洛式(HRE)
: 麻煩各位大大嚕
: 謝謝~~
: 感恩~~~
洛氏硬度我只聽過HRB跟HRC
但根據我一個在做逆向工程的國小同學李家宏的說法
家宏說他不知道維式轉洛式的公式
但家宏知道維式轉拉伸強度的公式
由HBN換算TS (拉伸強度)
HBN = Brinell Hardness
TS (psi) = 500 x HBN
TS (ksi) = 0.5 x HBN
TS (MPa) = 3.45 x HBN
TS (Kgf/mm2) = 0.345 x HBN
家宏說你再找找 拉伸跟洛式的轉換
因為家宏公司用的機器是維式硬度 這種實驗操作步驟對 大部分值不會差太多
反正出來的值 大於所設安全係數(或因子) 就OK了

滑鼠左鍵複製紅色方塊之後再按滑鼠右鍵貼上.你會後悔!!!請不要照著做!

驚見家宏，快拜！
