“…Ali et al manufactured the hybrid closed-cell AF and investigated the effect of the different parameters, such as temperature and wt. % foaming agent and mixing speed on the porous area and pore size using the Taguchi DOE approach [39,40]. The study shows that amount of the foaming agent is the highly signi cant factor, followed by stirring speed and temperature.…”

Aluminum metal foam has become an advanced popular material because it has excellent mechanical and electrical properties and is lightweight. The present work developed the Aluminium metal foam specimen using wax powder as a blowing agent through the powder metallurgy method. The effect of process parameters such as powder size, stirring speed, sintering temperature, and foaming agent content on the mechanical behavior of the developed specimens has been studied experimentally. In the design of experiments, the Taguchi orthogonal L9 array has been implemented. The percentage of Porosity was estimated using the Archimedes principle, and mechanical behaviors such as exural, tensile, and compressive strength were determined. The ANOVA analysis of variance it's been carried out to check the signi cant parameters affecting the mechanical behavior of developed specimens. It was observed that the powder size is the highly signi cant parameter, followed by stirring speed, the content of the foaming agent, and sintering temperature. The Maximum Porosity 71.30%, Compresssion strength 12.01MPa, Tensile strength 6.16 MPa, Flexural strength 5.18 MPa. The microstructure study reveals that there is no any adequet compostion in the specimen. The novelty in this research work is using a novel foaming agent as a Wax powder to develop aluminium metal foam and attained good properties.

“…Limited research data on the mechanical characteristics of Aluminium alloy foam and the impacts of cryogenic treatments have come through authorized patents and previous publications. Cryogenic treatments' effect on the mechanical characteristics of Al 6101 closed-cell foam has recently acquired higher demand (15)(16)(17) . Despite this, no previous research has provided sufficient evidence to establish the wear resistance of Al6101 alloy foam treated with deep cryogenics.…”

Objectives: This study deals with the optimization of wear properties of Al 6101-alloy foam treated with different temperature zones such as Untreated (UT), Heat Treated (HT), Cryogenic Treated (CT), and Cryogenic Heat Treated (CHT), respectively. The results of this study concerning confirmation tests enable us to validate the proposed optimization findings for the coefficient of friction and specific wear. Methods: The Al 6101 foam samples used in this study are exposed to different heat and cryogenic treatments as well as wear tests using the pin-on-disk apparatus setup with the Taguchi optimization technique. The wear parameters are enhanced further using the Analysis of variance (ANOVA) technique, and this model is processed using the MINITAB software. The Al 6101 foam samples are evaluated using important wear testing parameters like Heat Zone, Load (N), Speed (rpm), and Sliding Distance (m), as well as the output parameters such as coefficient of friction and specific wear (mm 3 /Nm). Findings: The optimum combination of the coefficient of friction and specific wear, according to the graphic and analytical results of Taguchi's optimization, is with 40 N load, 400 rpm speed, and 1500 m distance for a cryogenic zone and 40 N load, 400 rpm speed, and 2000 m distance for a cryogenic heat zone, respectively. The interaction of sliding distance, load, and speed, which has probabilities of 17.42, 8.95, and 7.74, respectively, is followed by the coefficient of friction, which has a greater probability percentage of 48.01 for the heat zone. The ANOVA for the specific wear has a higher probability percentage of 48.82 for the load and is followed by the interaction of heat zone, sliding distance, and speed, which have probabilities of 37.59, 6.02, and 2.85, respectively. Novelty: Considering Al 6101 foam, which is mostly a nonferrous material, this experiment once again confirmed that novel cryogenic treatment has a noteworthy improvement in coefficient of friction and specific https://www.indjst.org/ wear. Additionally, Taguchi's optimization and ANOVA analysis proved that the Al 6101 closed-cell foam specimen in the CHT zone exhibited optimal results when compared with other heat zones. The results confirmed that the CHT processing improves the wear resistance of the Al 6101 closed-cell foam effectively when examined with other different heat zones.
