Abstract

Reversed plane bending fatigue tests were conducted on SiC particle reinforced and SiC whisker reinforced aluminum composite. The initiation and growth behaviors of small surface fatigue cracks were continuously monitored by the replica technique and the causes of fracture and fracture mechanism were investigated by SEM. The relationship between da/dn and $K_{max}$ show that da/dn increases in high stress level while decrease and again increases with increasing of $K_{max}$ in low stress level for two materials.

본 연구는 SiC 입자 강화된 알루미늄기 복합재료와 SiC 휘스커 강화된 알루미늄기 복합재료를 이용해서 평면굽힘피로시험을 행했다. 표면미소피로균열의 발생 및 진전거동은 레프리카법으로 연속관찰을 했고 파괴원인과 파괴기구를 규명하기 위해서 주사전자현미경을 이용했다. 두 재료 모두 da/dn - $K_{max}$ 관계에서 고응력 레벨에서는 $K_{max}$의 증가에 따라 da/dn이 증가 했지만, 저응력 레벨에서는 da/dn이 감소하다가 증가하는 것을 알 수 있다.
