TY - JOUR ID - TI - The Effect of (á-Al2O3) Volume Fraction on The Mechanical Properties of (Al-Alumina) Metal Matrix Composite AU - Fawziea M. Hussien AU - Baydaa Abdul-Hassan Khalaf PY - 2011 VL - 29 IS - 13 SP - 2765 EP - 2772 JO - Engineering and Technology Journal مجلة الهندسة والتكنولوجيا SN - 16816900 24120758 AB - This research tends to study the effect of change in volume fraction of alpha phase alumina on mechanical properties of a metal matrix composite specimens contain (Al- áAl2O3). Specimens were prepared with the following volume fractions (10, 15, 20, 25, 30, 35, 40, and 45). Then effectof this change on hardness, maximum stress and strain,Young’s modulus, impactand wear resistance has been studied. Results of testing showed that while hardness, maximum stress, Young’s modulus, and impact strength increased markedly with volume fraction of alumina, wear rate, and maximum strain decreased with increasing of volume fraction.
