Figure 7 gives the liquidus of the samples compared with the melting temperatures and the breakpoint temperatures, which indicates that the measurement and the calculation are consistent.
The experiment was carried out with an Al-7 wt.% Si alloy with superheat of 10% above the liquidus temperature, as shown in previous articles, as well as the enlarged partial phase diagram of the Al-Si system, which permits a clear visualization of phases and transformation temperatures in the hypoeutectic range of Al-Si alloys [42-44].
The measured solidification range for the bismuth-containing alloy was approximately 90[degrees]F (50[degrees]C) greater than the leaded alloy solidification range and approximately 81[degrees]F (45[degrees]C) smaller than the lead/bismuth free alloy The liquidus of the bismuth containing alloys was lower than both the leaded and lead/bismuth free alloys.

one of the key characteristics relevant to semi-solid processing is the width of the interval between the solidus and liquidus. The interval recommended specifically for minithixoforming is 10-30% [5, 6].
The liquidus and solidus interface position during the freezing process for both parabolic and hyperbolic models are shown in Figure 4 and Figure 5 respectively.
It is a continuous casting process that works by applying a low superheat to the metal at a uniform temperature near to or just above the liquidus temperature.
Liquidus Marketing (http://liquidus.net) has built a solid niche for itself by helping prospective buyers get the details they need about used cars: It currently streams 1.6 million videos a month to a variety of car sites.
The American Welding Society (AWS) defines brazing as a group of joining processes that cause the coalescence of materials in the presence of a brazing filler metal that has a liquidus temperature above 840[degrees]F/450[degrees]C, but below the solidus temperature of the base materials.
