Question: 4
A sheet of copper is exposed to oxygen at 1000°C. After 100 h, 0.245 g of copper are lost per
cm' of surface area; after 250 h, 0.385 g/ cm² are lost; and after 500 h, 0.560 g/ em are lost.
i. Determine whether oxidation is parabolic, linear, or logarithmic
ii. Calculate the time required for a 0.76-cm sheet of copper to be completely oxidized. The
sheet of copper is oxidized from both sides.
Two 0.5-cm-diameter rods of 1020 steel (σts = 395 MPa) are to be joined with a silver braze alloy 0.025 cm thick (σys = 145 MPa) to produce one long rod. The ultimate strength of this brazed structure is found to be approximately 345 MPa. If it is necessary to reduce the diameter of the rods to 0.25 cm with no change to the braze joint itself, will the strength (in MPa units) increase, decrease, or remain the same? If it changes, by how much?
