The effect of processing route and reinforcement geometry on isothermal creep behaviour of particulate and short fibre MMCs

Influence of processing route and reinforcement content on the creep fracture parameters of aluminium alloy metal matrix composites

“…This trend was previously found in [14] and has also been assessed here for materials reported in [22,29] and for the present 6061Al-40vol%SiC w composite, figures 3a) and 3b) These figures are double logarithmic plots of the strain rate as a function of the stress in which the creep data of this composite appear together with that of 6061Al-15vol%SiC w composite and 6061Al alloy of refs. [12,14].…”

“…Data from the open literature has been analyzed for this investigation [14,[21][22][23][24][25][26][27][28][29].…”

“…The importance of the MG equation resides on the fact that it is obeyed by most engineering materials. In is original and general form this equation reads: [11,[17][18][19][20]. Under this restriction, it is agreed that this empirical equation reveals that creep strain is the macroscopic manifestation of the damage accumulated during deformation and that the fracture mechanisms are associated with the deformation mechanisms.…”

Damage evolution in Saffil alumina short-fibre reinforced aluminium during tensile testing

“…The mechanical behaviour of this class of materials has, therefore, been the subject of several investigations, focused mainly on their tensile behaviour at ambient [3][4][5][6][7][8][9][10][11][12][13] and elevated temperatures [5,14,15], and their behaviour in creep [16][17][18][19], fatigue [20][21][22][23][24] and their fracture toughness [25][26][27].…”
