After the solution treatment at 415°C for 12 h, almost β-Mg17Al12 phases dissolved into the matrix. After ageing treatment at 200°C for 14 h, the LPSC alloy attained the peak hardness with restrained age-hardening kinetics. The discontinuous precipitates initiated at the grain boundaries and then continuous precipitates occurred in the grain interior. The LPSC alloy exhibits higher mechanical properties in both as-cast and heat-treated alloys compared with the gravity casting (GC) process alloy.","PeriodicalId":13939,"journal":{"name":"International Journal of Cast Metals Research","volume":"35 1","pages":"161 - 168"},"PeriodicalIF":1.4,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44697643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wear tests are carried out on a pin-on-disc tribotester with four different process parameters viz. wt-% of reinforcement, load, sliding velocity and sliding distance. For assessing the tribological performance of composites, grey relational analysis is adopted. The percentage significance of all the parameters on tribological performance has also been evaluated by analysis of variance. Based on Grey-Taguchi approach, the optimal parametric combination is 9 wt-% of reinforcement, 10 N load, 2 m s−1 sliding velocity and 1000 m sliding distance. The optimal parametric combination based on the highest ranking of grey relational grade is validated by a confirmation experiment. Based on the results, it can be concluded that Grey-Taguchi method is an effective tool used for optimising the tribological performance of Al2024-TiB2 composites.","PeriodicalId":13939,"journal":{"name":"International Journal of Cast Metals Research","volume":"35 1","pages":"144 - 151"},"PeriodicalIF":1.4,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44872613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper introduces the sequential probability ratio under neutrosophic statistics to deal with the data having imprecise and uncertain data.

The effect of process parameters on the dimensional accuracy of the bauxite shell mould was investigated. Taguchi’s design and Analysis of Variance (ANOVA) approach was used to evaluate and optimise the process parameters viz. wall thickness, wall height and filling pattern for dimensional accuracy. The results indicate the wall thickness, filling pattern and wall thickness are the most significant parameters affecting the dimensional accuracy in X, Y and Z directions, respectively.

The current research work uses a unique experimental design that involves performing surface and subsurface microscopy and spectroscopy at 0.5 mm intervals from the as-cast surface to a depth of up to 3.5 mm for three samples. The objective is on evaluating microstructure for determining graphite flake size, distribution, grouping, pearlite and ferrite percentage, and different elements.
