Assignment Details Aluminium alloys are very widely used in the industry as structural metals, second only to steel. Pure aluminium is very soft, light in weight and low melting point which makes it quite popular for various applications. However, adding alloying elements to aluminium enhances various physical properties making it even stronger and versatile for numerous engineering applications. Answer the following questions 1. Identify the following information for pure aluminium: Atomic number Atomic mass Atomic radius Crystal structure Density Periodic...

Sketch the aluminum-silicon phase diagram from the following data to estimate the proportion of pure silicon in the eutectic alloy just below the eutectic temperature and sketch the possible microstructure.
• It is a eutectic system. • The melting point of pure aluminum is 6600C • The melting point of silicon is 1410 0C • The eutectic temperature is 5800C • Aluminum is insoluble in silicon • The eutectic composition is 85% Al + 15% Si • The Al-rich phase (α) is a solid solution of Si in Al and the maximum solubility of Si in α is 3% at the eutectic temperature • At 500°C the solubility of Si in α has fallen to 0% and...

2) From the Cu-Ag phase diagram, determine the melting temperature of pure Cu and pure Ag. Determine also the eutectic temperature. 3) There are two liquidus line on the phase diagram. Let us assume that you have measured several cooling curves of samples covering from 0-100 wt% Ag composition range. The data points (phase transition points) on both liquidus lines are determined as in the following table: Left liquidus line Right liquidus line Wt% Ag Temperature (°C) Wt% Ag Temperature...

Material Science!!!
The Cu-Sn phase diagram has historical significance as this alloy is known as bronze. The ability to make a bronze alloy changed civilization since bronze has a higher yield strength than pure copper. Cu-Sn alloys also have modern applications in electronics as a basis for the replacement of lead based solders. Answer the following questions, relative to this diagram What is the melting point of pure Cu? What is the melting point of pure Sn? What is the...

Question: Create Young’s modulus-melting point (E-Tm)
chart (level 2) for metals and alloys. Use ‘guideline’ function to
determine which slope among 0.5, 1 and 2 in the E-Tm
chart best describes the dependence between E and Tm.
Justify this dependence from the origin of these two
properties.
I had already drawn the picture. Could you explain the
reason why Yong's modulus and melting point have a linear
relationship? Justify this dependence from the origin of these two
properties.!!!!
