Ultralow-temperature superplasticity and its novel mechanism in ultrafine-grained Al alloys
Materials Research Letters, 2021 The important benefits of ultrafine-grained (UFG) alloys for various applications stem from their enhanced superplastic properties. However, decreasing the temperature of superplasticity and providing superplastic forming at lower temperatures and higher

Advanced Engineering Materials, EarlyView.Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing
Advanced Engineering Materials, EarlyView.This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Ultrafine-grained materials: a personal perspective [PDF]
International Journal of Materials Research, 2007 Abstract The Chinese philosopher Lao Tzu wrote that “a journey of a thousand li begins with a single step”.† My first step on the road to ultrafine-grained materials occurred on 5 May, 1989, when I boarded a plane in Los Angeles on the way to Ufa via Copenhagen and Moscow.
