چکیده

In this paper, a finite element (FE) cutting model for particle-reinforced metal matrix composites (PRMMCs) considering material damage was developed to predict SiC particle failure, forces, and machined surface topography in SiCp/Al composite machining, analyze the dynamic mechanisms of chip formation failure evolution. The validity simulation verified by comparing results with forces obtained from milling machining experiments. It found that complex stress-strain fields exist mesoscopic non-homogeneous structures, alternating reticulation tensile compressive stress between particles observed; due tool-workpiece interaction exists both direct indirect ways; local deformation during affect shaping, resulting serrated chips, pitting on surface, residual fragments.

Wear of ceramic particle-reinforced metal-matrix composites

Wear experiments have shown that when the applied normal stress exceeds a critical value, a transition occurs from the regime of mild wear to that of adhesive wear. As a result, the wear rate of particle-reinforced aluminium composites increases by a hundred-fold. Based on dislocation and delamination theories, a criterion is proposed for determining the critical transition load, and a quantita...

Casting of SiC Reinforced Metal Matrix Composites

Composites based on two aluminium alloys (A536 and 6061) reinforced with 10% or 20% volume fraction of SiC particles were produced by gravity casting and a novel two-step mixing method was applied successfully to improve the wettability and distribution of the particles. The SiC particles were observed to be located predominantly in the interdendrit ic regions, and a thermal lag model is propos...

Strain gradient effects on deformation strengthening behavior of particle reinforced metal matrix composites

Dislocation models with considering the mismatch of elastic modulus between matrix and reinforcing particles are used to determine the effective strain gradient h for particle reinforced metal matrix composites (MMCp) in the present research. Based on Taylor relation and the kinetics of dislocation multiplication, glide and annihilation, a strain gradient dependent constitutive equation is deve...

Damage accumulation and mechanical properties of particle-reinforced metal–matrix composites during hydrostatic extrusion

The effects of hydrostatic extrusion on particle cracking and on the subsequent tensile properties of some prototypical particlereinforced metal–matrix composites are investigated. In most cases, tensile failure occurs through a plastic instability in accordance with the Considere criterion for necking. The corresponding failure strain is therefore dictated by the global flow and hardening char...

Mechanical and Tribological Behavior of Aluminum Alloy LM13 Reinforced with Titanium Dioxide Metal Matrix Composites

In the present research work physical, mechanical and tribological behavior of Aluminum (Al) alloy LM13 reinforced with Nano-sized Titanium Dioxide (TiO2) particulates were fabricated, mechanical and tribological properties were investigated. The amount of nano TiO2 particulates in the composite was added from 0.5% to 2% in 0.5 weight percent (wt %) increments. The Al-LM13-TiO2 Metal Matrix Com...
