... different post-ageing media: air, oil, furnace, sand and water. Optical microscopy was used for microstructural observation, while hardness testing, tensile testing, surface roughness measurements after turning and field emission scanning electron microscopy-based fractographic analysis were conducted...

... ranges of AFR and SOD were 5–20 L min⁻¹ and 1–4 mm, respectively, for superior surface quality. Findings The results indicated that moderate heat input significantly improves hardness due to enhanced metallurgical bonding and controlled dilution. Maximum hardness of 415 was achieved...

... that the tensile strength and hardness increased by using 22.41% and 45.5%, respectively, at 4.75 Wt.% each reinforcement, i.e. ES and RHA, and 1% Cr. The toughness and ductility of metal matrix composite (MMCs) have decreased up to 23.31% and 19.23% respectively by using 1% Cr, 4.75 wt. % ES and by 4.75 wt. % RHA...

... HAZ and weldment. In HAZ, there are bright and the dark regions marked with steaks, which is similar to martensitic structures. It is evident that the hardness in HAZ is more than the weld zone, this attributed to the presence of martensite (Lakshminarayanan and Balasubramanian, 2013...

... casting have been optimized by using “Response Surface Methodology.” Findings To maximize the hardness and tensile strength the values of optimal input casting parameters as found by the experimental results (response surface methodology) are as follows: the pre-heating temperature of collagen...

... of Group 3 were aged with thermal (563°C and 5563°C) and pH (2–14) cycles. All 24 samples were tested with a Profilometer and a Vicker hardness tester was used for their surface roughness and hardness measurement, respectively. Findings In statistical examination on SPSS Statistics 20 (IBM) software...

...-scale, ultrasonic velocity and internal friction were employed to evaluate the Young modulus (E), whereas for nano-scale the nanoindentation method was a very useful tool to obtain the elastic modulus and hardness. These results reveal the strong influence of vanadium admixture on mechanical properties...
