Effect of Milling and Wire Electric Discharge Machining on Recast Layer Formation and Tensile Behavior of Metallic Materials

MetalMat, EarlyView.
ABSTRACT Machining of materials is an invaluable technique to give specific shapes and dimensions of desired materials. Different machining processes give rise to different surface characteristics that include not only surface roughness but also specific surface morphology, such as the recast layer.

On the Mechanical and Thermal Behavior of PLA, PBAT, and PHBV‐Based Ternary Blends and the Effect of Short Flax Fibers as Reinforcing Agents

Polymer Composites, EarlyView.
Preparation and testing of biodegradable polymer ternary blends and composites with short flax fibres. ABSTRACT Bioplastics offer environmental benefits but they are costly and exhibit lower mechanical and thermal performance compared to fossil‐based counterparts. Poly(butylene adipate‐co‐terephthalate) (PBAT) exhibits high ductility but relatively low

Hydrogen environment embrittlement of astroloy and Udimet 700 (nickel-base) and V-57 (iron-base) superalloys [PDF]

The sensitivity to hydrogen environment embrittlement of three superalloys was determined. Astroloy forgings were resistant to embrittlement during smooth tensile, notched tensile, and creep testing in 3.5-MN/sq m hydrogen over the range 23 to 760 C. The

Masterbatch‐Assisted Fabrication of Polylactic Acid/Reduced Graphene Oxide Nanocomposites Exhibiting Mechanical Enhancement and UV‐C Aging Resistance

Polymer Composites, EarlyView.
Masterbatch‐Assisted Fabrication of Polylactic Acid/Reduced Graphene Oxide Nanocomposites. ABSTRACT Polylactic acid (PLA) is a promising bio‐based polymer; nonetheless, its extensive application is still limited by poor fracture toughness, low thermal stability, and strong susceptibility to degradation induced by ultraviolet (UV) radiation.
