“…Unlike in many cast alloy and composite the dendrites with columnar structure are found to form in conventional casting technique. In present case using mechanical stirrerto create vortex and stirring molten metal, the dendrites are broken and equi-axed globular grains are formed in both LM26 alloy and its composites [14].…”

This work was focused on development of LM26 composites reinforced with Chromium Oxide particles by utilizing the technique of stir casting. Percentage of chromium oxide was varied between 0 to 10wt%. A study of the mechanical properties as well as microstructure of the developed composites had been performed. With the assistance of optical microscope, the microstructural studies of LM26 alloy as well as composites have been conducted. Investigations were carried out on the LM26 alloy as well as composites for properties such as tensile strength as well as hardness. Microstructure confirms that the chromium oxide particles' distribution has been uniform. The hardness of composites was found to higher than unreinforced alloy and increases over time as weight percentage increases of Chromium Oxide particles from 0% to 10%. For LM26/10% Chromium Oxide composite showed highest yield and tensile strength compared to other composites and unreinforced LM26 alloy. Keywords: Aluminium matrix composites, stir casting, Microstructure, Mechanical properties.

“…From the results, it was revealed that the tensile strengths of the heat treated composites are higher compared to un-heat treated composites. The improvement in ductility of MMCs can be attributed to the coupling effect of a numerous small hard ceramic particles due to growth restriction and also thermal modification at the time of heat treatment [26]. As shown in Fig.…”

The effects of SiC-Al2O3 particle in the Al alloy on the mechanical and wear characteristics of stir-casted Composites have been reported. The Al7075 is reinforced with 2, 4, 6 and 8 wt. % of (SiC + Al2O3) to manufacture the hybrid composite. Ceramic particulates were added into Al alloy to achieve the low wear rate and improving mechanical properties. Hardening of casted specimens at 480ºC for the duration of 2 hrs and the specimens were quenched into two different quenching media (water and ice cubes). Finally, age-hardening were carried out at the temperature of 160ºC for the duration of 4 hrs and cooled at room temperature. The tensile strength, hardness and wear behaviour of MMCs are evaluated on the un-treated and heat treated composite. The tensile strength and hardness of MMCs increases by incorporating SiC-Al2O3 particulates. The wear behaviour of the MMCs containing SiC-Al2O3 particulates revealed the high wear-resistance. The heat-treatment had considerably improved the properties when compared to the un-heat treated composites. The composites with the highest tensile strength, hardness and enhanced wear resistance were found in the composites quenched in ice cubes. Worned surfaces of the composite specimens were studied by using SEM and XRD analysis

“…Metal cutting processes take advantage of RSM optimization [57,58]. In addition, RSM has entered materials sciences [59]. With regard to SP, prevention of Almen strip wastes and time during the detection of pre-shot peening conditions make the usability of statistical methods meaningful.…”

Influences of Shot Peening Parameters on Mechanical Properties and Fatigue Behavior of 316 L Steel: Experimental, Taguchi Method and Response Surface Methodology

2021

Severe plastic deformation methods like shot peening (SP) are known as efficient surface treatments and grain refining processes which afford more effective properties in metallic materials. In the current research, a comprehensive study was carried out on SP of AISI 316 L steel. It included 42 different SP treatments with a wide range of Almen intensities of 12–27 A and various coverage degrees (100%–1500%). Several experimental tests were conducted in order to explore the microstructure, grain size, surface topography, hardness, wettability, and residual stresses of the specimens. Next, two different approaches including Taguchi method (TM), and response surface methodology (RSM) were deployed for modeling, analysis, and optimization. RSM and TM were used to examine the influence of the effective parameters. Based on the optimized results, the fatigue behavior of the selected treatments was investigated experimentally in both smooth and notched specimens. Graphical abstract
