Effect of strontium and cooling rate upon eutectic temperatures of A319 aluminum alloy [PDF]
, 2004 DTA analysis was used to investigate the solidification reactions of alloy A319 with either 12 or 136 ppm of Sr added. Strontium does not affect primary solidification of (Al) dendrites but modifies the kinetics of the (Al)–Si eutectic. The effects of Sr

Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)
Land Degradation &Development, EarlyView.ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...
