Abstract:
Disclosed herein is a sintered composition comprising iron; about 0.05 to about 1 wt % molybdenum; about 3 to about 4.5 wt % silicon; about 0.05 to about 0.5 wt % chromium; about 0.011 to about 0.015 wt % magnesium; all weight percents being based on the total weight of the composition; the composition being devoid of carbon except for trace amounts; and wherein the composition is sintered. Disclosed herein too is a method comprising blending a powdered composition that comprises iron; about 0.05 to about 1 wt % molybdenum; about 3 to about 4.5 wt % silicon; about 0.05 to about 0.5 wt % chromium; about 0.011 to about 0.015 wt % magnesium; all weight percents being based on the total weight of the composition; the composition being devoid of carbon except for trace amounts; compacting and sintering the composition.
