Soldering is similar to welding but on a very smaller scale. It uses a filler metal that is melted and placed between the target metals. The target metals are fused due to the high heat and the action of the filler metal. Soldering is one of the oldest metal fabrication processes, with ...
During the recrystallization stage, the material is heated above its recrystallization temperature, but below its melting temperature. This causes new grains without preexisting stresses to form. Grain Growth Stage During the grain growth, the new grains fully develop. This growth is controlled by all...
Recrystallization: Recrystallization is when a substance is dissolved so that it can be purified in a hot liquid. When the solvent cools down, the solution is saturated with the solute that crystalizes, or forms a solid again. Carbonate minerals can recrystallize due to their structure. ...
including non-polar solvents such as petroleum ether and hexane, and low-polarity solvents such as ether. It is worth mentioning that in the literature, Bis(pinacolato)diboron is often further purified by recrystallization from petroleum ether (dissolving at high temperature and precipitating at low ...
Solubility is a physical property that describes the integration of a solute with a solvent, making a homogenous (uniform) mixture of the two substances. Each substance has its solubility limit, varying from extremely small to extremely large. For example, sodium chloride...
Cold forging typically refers to forging a metal at room temperature, though any temperature below recrystallization is possible. Many metals, such as steel high in carbon, are simply too strong for cold forging. Despite this hindrance, cold forging does edge out its warmer equivalent when it com...
Mass spectrometry is a substance from a crime scene that is analyzed by a mass spectrometer in order to find the molecular makeup. Explore how mass spectrometry can be used to identify all kinds of evidence such as cloths, glass, dyes, metals, and even human tissue. Related...
“clean” and white showing low dislocation density but the lath boundaries are still visible. The right image shows the steel tempered at 1290°F for 12 hours where the beginning of martensite recrystallization is visible, where the round grains of ferrite have begun replacing the martensite ...
verb (used with object), hot-drew, hot-drawn, hot-draw·ing. Metalworking. to draw (wire, tubing, etc.) at a temperature high enough to permit recrystallization.
Often used when precision is required, cold rolling occurs below the recrystallization temperature of the steel. Multiple supported rollers are used to shape the steel. This process creates a more attractive, uniform finish. However, it can also deform the steel’s structure and often requires heat...
