【摘要】：對建筑用Si C增強(qiáng)鋁基復(fù)合材料坯料進(jìn)行了鍛造試驗,對鍛造前后試樣的耐磨損性能和沖擊性能進(jìn)行了測試與分析。結(jié)果表明:鍛造顯著提高了試樣的耐磨損性能和沖擊性能。與鍛造前相比,鍛造后試樣磨損30 min后的磨損體積減小61%,25℃沖擊吸收功增大29%,沖擊斷口表現(xiàn)為以脆性斷裂變?yōu)轫g性斷裂為主、脆性斷裂為輔的混合斷裂。
[Abstract]:The forging test of Si C reinforced aluminum matrix composite billet for building was carried out, and the wear resistance and impact properties of the samples before and after forging were tested and analyzed. The results show that the wear resistance and impact properties of the samples are significantly improved by forging. Compared with before forging, the wear volume of forged specimens decreased by 61% after 30 min, and the impact absorption work increased by 29% at 25 鈩，
