Powder metal (PM) processes are becoming better known for their ability to produce complex parts with robust mechanical properties while keeping manufacturing costs at bay. The 2006 Powder Metallurgy Design Awards, a competition sponsored by the Metal Powder Industries Federation, illustrated a collection of the best powder metal components used in lawn-and-garden, off-highway, appliance, hardware, electronics and tool applications. Here's a look at three of the winning parts, all of which make smart use of secondary operations to enhance PM's off-the-press properties.

Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
