It is well-known that the harsh operational conditions of turbine blades lead to a gradual change in the microstructure of underlying Ni-based superalloy of blades. According to this, a rejuvenation process should be conducted on turbine blades superalloys to recover their microstructures. The first and main step of rejuvenation process is the determination of appropriate solution condition in ...

Rejuvenation is the configurational excitation of amorphous materials and is one of the more promising approaches for improving the deformability of amorphous metals that usually exhibit macroscopic brittle fracture modes. Here, we propose a method to control the level of rejuvenation through systematic thermal processing and clarify the crucial feasibility conditions by means of molecular dyna...

Background: With the increase in life expectancy, middle aged and elderly people comprise a substantial percentage of the population worldwide. Since aging often manifests itself in the human skin, skin rejuvenation methods have gained a lot of popularity. Current medical modalities such as botulinum toxininjection, fillers, and laser therapy can provide symptomatic relief of skin aging s...

Abstract A hot isostatic pressing rejuvenation heat treatment is applied to a CMSX-4 type SX superalloy after it has been subjected low-cycle fatigue test rupture. The evolution of microstructural defects, such as pores and cracks which are present fatigue, tracked in 3D by X-ray tomography before rejuvenation. From the rejuvenated specimen, series metallographic cross sections were prepared in...

Topical skin care regimens are a mainstay treatment for aging skin. All patients seeking skin rejuvenation can benefit from this low-risk intervention. This article reviews available nonprescription topical treatments for rejuvenation including moisturizers, antioxidants, retinols, and sunscreen.
