Grain Initiation and Grain Refinement: An Overview

Metals, 2022
Heterogeneous nucleation and grain initiation are two different processes in early-stage solidification (ESS), although both are deterministic. Heterogeneous nucleation refers to the formation of a 2-dimensional (2D) nucleus (a crystal plane of the solid)

An Analytical Study for Explosive Grain Initiation [PDF]

Crystals
The most common form of solidification of metals is heterogeneous nucleation, in which the particles, regardless of whether they are endogenous or exogenous, nucleate the primary crystal phase, becoming solid crystal particles and, subsequently ...

Competition for Nucleation and Grain Initiation during Solidification [PDF]

Metals, 2022
Without the addition of any grain refiner, the inclusion particles in a melt will induce heterogeneous nucleation and grain initiation during the solidification of metallic materials.

Efficiency of Sucrose to Starch Metabolism Is Related to the Initiation of Inferior Grain Filling in Large Panicle Rice

Frontiers in Plant Science, 2021
The poor grain-filling initiation often causes the poor development of inferior spikelets (IS) which limits the yield potential of large panicle rice (Oryza sativa L.). However, it remains unclear why IS often has poor grain-filling initiation.

Altering tensile and crack initiation behavior in a metastable β titanium alloy via designing grain size and precipitates

Journal of Materials Research and Technology
Microstructure can play a vital role in defining mechanical properties of metallic materials. To elucidate this correlation in the case of Ti–15Mo–3Nb–3Al-0.2Si (TB8) alloy, herein, we designed various microstructures via heat treatment exploring the ...

Effect of ultrasonic peening treatment on the fatigue behaviors of a magnesium alloy up to very high cycle regime

Journal of Magnesium and Alloys, 2022
Ultrasonic fatigue tests are performed on a magnesium alloy with and without ultrasonic peening treatment (UPT). Surface enhancement layer leads to the complete change of crack initiation sites.

Effect of misorientation of grain boundaries on the discontinuous precipitates of Cu–Ni–Si alloy

Journal of Materials Research and Technology, 2023
In this study, the effects of differences in grain size, grain boundary type and misorientation on the initiation of discontinuous precipitates are investigated for the Cu–5Ni–1.25Si alloy.

Roles of phytohormone changes in the grain yield of rice plants exposed to heat: a review [PDF]

PeerJ, 2019
During its reproductive phase, rice is susceptible to heat stress. Heat events will occur at all stages during the reproductive phase of rice as a result of global warming.
