試驗(yàn)原理及試驗(yàn)裝置 5.1 維氏硬度和努氏硬度的試驗(yàn)原理—維氏壓痕硬度試驗(yàn)和努氏壓痕硬度試驗(yàn)的一般原理包括兩個(gè)步驟，顯微硬度測(cè)試儀一體化。 5.1.1 步驟1—在垂直于表面的方向使規(guī)定的合適壓頭壓到試樣上面并施加試驗(yàn)力F。將試驗(yàn)力保持一定時(shí)間后卸除。 5.1.2 步驟2—對(duì)于維氏硬度試驗(yàn)，測(cè)量?jī)蓷l對(duì)角線的長(zhǎng)度并計(jì)算平均對(duì)角線長(zhǎng)度(其可被用于推導(dǎo)維氏硬度值)。對(duì)于努氏硬度試驗(yàn)，測(cè)量長(zhǎng)對(duì)角線的長(zhǎng)度(其可被用于推導(dǎo)努氏硬度值)。 5.1.3 當(dāng)在加載循環(huán)結(jié)束后移走壓頭時(shí)，大多數(shù)材料都將展現(xiàn)出一些彈性恢復(fù)。但如果要利用壓痕的對(duì)角線長(zhǎng)度計(jì)算硬度值，則應(yīng)假設(shè)壓痕仍保持卸除試驗(yàn)力之后的壓頭形狀。在努氏試驗(yàn)中，則應(yīng)假設(shè)壓痕的長(zhǎng)對(duì)角線與短對(duì)角線之比壓頭的相同。 5.2 試驗(yàn)機(jī)—試驗(yàn)機(jī)應(yīng)能支撐試樣并控制壓頭以預(yù)先設(shè)定的試驗(yàn)力壓入試樣，并且應(yīng)配備有一個(gè)光學(xué)顯微鏡，以選擇期望的試驗(yàn)位置并測(cè)量試驗(yàn)中所產(chǎn)生的壓痕尺寸。試樣表面的平面宜垂直于壓頭的軸線(即施加力的方向)。 5.2.1
