Evaluation of fatigue and impact behavior of titanium carbide reinforced metal matrix composites

A Simulation of Low and High Cycle Fatigue Failure Effects for Metal Matrix Composites Based on Innovative J2-Flow Elastoplasticity Model

“…Typical S - N curves for the fatigue failure of MMCs under cyclic loading conditions are schematically shown in Figure 1 for different cases of the weight percentage of reinforcing particles. As reported in experiments (cf., e.g., [ 4 , 5 , 6 , 7 ]), the S - N curve goes up with increasing weight percentage of reinforcing particles. Each curve becomes nearly flat at very high cycles.…”

“…With improved fatigue and impact performance [ 1 , 2 , 3 ], metal matrix composites (MMCs) have in the recent past been used toward reducing weights of structural components and parts. For instance, Al-matrix composites with ceramic TiC reinforcing particles exhibit excellent mechanical strength with improved fatigue resistance and creep resistance [ 4 , 5 , 6 , 7 ] and have been used in automobile industry. A detailed review for literature of fatigue of reinforced composites and recent applications may be found in LLorca [ 8 ].…”

“…Certain representative results for MMCs are as follows. Quast et al [ 13 ] investigated the out-of-phase thermomechanical fatigue behavior of Ultra SCS-6/Ti-24Al-17Nb-xMo (at.%) MMCs; the fatigue behavior of two 2009/SiC/15p-T4 DRA (discontinuously reinforced aluminum) composites in the very high cycle fatigue was investigated by Huang et al [ 14 ]; Ni et al [ 15 ] studied residual stresses and high cycle fatigue properties of friction stir welded SiCp/AA2009 composites; fatigue failure mechanisms of microsphere Al2O3-Al particulate MMCs were determined from examination of the fracture surfaces and the crack profiles by Park et al [ 16 ]; Sivananth et al [ 7 ] evaluated the load bearing behavior of titanium carbide reinforced aluminum matrix composites and their suitability for automotive application; Feng et al [ 17 ] determined the relationship between the applied stress and fatigue life of a SiC fiber-reinforced titanium matrix composite and examined the fracture surfaces to study the fatigue damage and fracture failure mechanisms using SEM; and the creep–fatigue behavior of aluminum alloy-based MMC has been modeled using an idealized plane strain model [ 18 ]. Moreover, many other related studies may be found in [ 19 , 20 , 21 , 22 , 23 , 24 , 25 ].…”

Effect of Al 6061 Alloy Compositions on Mechanical Properties of the Automotive Steering Knuckle Made by Novel Casting Process

“…Here, we demonstrate the clear superiority of our method by fabricating steering knuckles with outstanding mechanical strength from the Al 6061 alloy, as shown in Figure 1. A steering knuckle is an important component of automotive suspension systems, and many attempts have been made to fabricate steering knuckles with Al alloys to reduce vehicle weight [8][9][10][11][12]. To improve the mechanical properties of steering knuckles, we evaluate various compositions of Al alloys by analyzing their thermal properties, such as thermal stress, shrinkage starting temperature (SST), shrinkage characteristics, and pore formation.…”

Microstructures and Mechanical Properties of Al3Ti/Al Composites Produced In Situ by High Shearing Technology

“…During the past decades, particle reinforced Al matrix composites have attracted much attention as engineering material due to their low density, high specific E‐modulus, strength, and high wear resistance . Typically, ceramic particles were selected as reinforcements to enhance the Al alloy, such as SiC, B 4 C, Al 2 O 3 , or TiC . However, owing to the poor wettability between the ceramic particles and the aluminum melt, it is difficult to introduce them into the Al melt and to get a homogeneous distribution of the particles in the matrix.…”
