They found two strong magnetic anomalies, possibly related to impact melts
, inside an unusually shallow, 150-km-diameter crater that lies in water about 3.
While the relative simplicity of this test has remained the same, melt
indexers have evolved considerably since they appeared in the 1950s.
A more quantitative evaluation can be obtained by calculating the specific gravity of the sample and correlating that with the dissolved hydrogen porosity content of the melt
They must be melted
at 250 F so they can be dispensed through a gun like thermoplastic hot melts
Assessing the level of hydrogen in the melt
can be done in several ways.
For in-cavity melt
pressure, models 4MO1 and 4MO2 quartz piezoelectric transducers are offered along with the associated cabling.
When a comet or asteroid collides with the moon or one of the terrestrial planets, it typically generates a shock wave powerful enough to melt
some of the rock.
Such instruments for measuring elastic properties of melts
include mechanical spectrometers and controlled-stress rheometers.
Even when they placed an island of atoms atop the copper (111) surface and gouged out a large hole nearby, the surface didn't melt
Auburn Foundry Plant 2 melts
Class 30 gray iron in three 10-ton coreless induction furnaces with 7000 kW medium frequency power supplies.
The core alloy developed for the athletic-shoe prototype, for example, melts
out in boiling water at 220 F.
Research is being done with the use of sound waves to measure inclusion content in aluminum melts
They also determined that at 330 GPa (similar to the pressure at the boundary between the solid inner core and the liquid outer core), iron melts
at 7,600 500 K.
a Michigan-based producer of steel shot that melts
using a dual 5000-kW induction system operating two 6-metric-ton coreless steel shell furnaces.
A research consortium composed of gray iron foundries and steel scrap processors was formed to document the effect of lead in cast iron melts
and investigate factors affecting lead recovery from a gray iron cupola charge.
