Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.

Question

**Transcription for Educational Website:**

**Problem Statement:**
Calculate the activation energy (in J/mol) for creep for an alloy having the steady state creep behavior shown in the figure. Use the data taken at a stress level of 300 MPa and temperatures of 650°C and 730°C. Assume that the stress component \( n \) is independent of the temperature.

**Graph Description:**
The graph is a plot of Stress (MPa) versus Steady-state creep rate \((h^{-1})\). The horizontal axis represents the steady-state creep rate on a logarithmic scale ranging from \(10^{-6}\) to \(10^{3}\). The vertical axis represents stress, measured in MPa, from 20 to 1000.

There are four lines representing different temperatures:

- **650°C**: Blue line, starting from lower left to upper right.
- **730°C**: Green line, showing a similar upward trend.
- **815°C**: Red line, positioned lower than the 730°C line.
- **925°C**: Orange line, lowest among the four, maintaining an upward trend.

Each line indicates how stress at a constant temperature affects the steady-state creep rate. Higher temperatures generally result in lower stresses for the same creep rate compared to lower temperatures.

The flow stress of a coarse-grained dilute copper alloy increased from 2 to 55 MPa when the dislocation density was increased from a low value of 10 cm via cold working to a modest value of 100 cm2. Calculate the flow stress for this alloy when heavy cold working introduces a dislocation density of 10¹2 cm². An equation similar to the Hall-Petch equation has been proposed for dislocations, and is: Tflow To ka Paisl where Tflow is the flow stress (i.e., the force per unit area necessary to get plastic deformation), pdisi is the dislocation density (the dislocation line length per unit volume), and To and ka are constants for a given material. The easiest way to solve this problem is to put values into this equation twice, subtract one expression from the other, and solve for ka. Then enter your value of ka into either original equation to determine To. Keep track of units, and then solve the problem stated above.

A tie rod made of quenched and tempered 4340 steel is used as a critical linkage in an industrial apparatus. The rod is subjected to an alternating cyclic tensile/compressive stress from 550 MPa to -550 MPa. An inspection of the rod revealed a 3.5 mm deep edge crack on the surface of the rod. Please answer the following question for the rod given the properties in the table and curve below and fracture toughness of 55 MPa√m. (NOTE: Y=1.12 for edge crack and use “a” not “2a” for the length of the crack) 1. What is the minimum crack size that would cause instantaneous fast fracture at the current maximum axial tensile loading, assuming plane strain conditions apply? If the resolution limit of the flaw detection apparatus were 1.5 mm, would this flaw be subject to detection? Show calculations to back up your conclusions.
