3D printing a hot commodity
Molybdenum metal is indispensable to several industries because of its strength at high temperatures. But some applications require complex and not so-easily-fabricated shapes. 3D printing is one approach to overcoming production issues with complicated parts, however, when produced in molybdenum metal, such parts often suffer from defects. A new process, alloying it with titanium carbide, may indicate a turning point.
Keeping Tabs
Under the guidance of supporting philanthropists, artists and architects, a group of school children turned trash into a timeless memorial. Keeping Tabs holds six million soda tabs, each symbolizing a life lost decades ago. Molybdenum-alloyed stainless steel provides the corrosion resistance to keep this sculpture beautiful and untarnished through the deicing salt-laden winters of the midwestern United States.
Replacing old rail bridges
The historic center of Stockholm, Sweden, stretches over 14 islands. The bridges that connect these islands are in constant use, so any maintenance closures cut off vital transportation arteries. A solution that spares future generations from disruption was therefore crucial for the renovation of the city's busiest rail bridges: the four Söderströms. The new molybdenum-containing duplex stainless steel superstructure will provide enough strength and corrosion resistance to outlast the 120-year design life, with minimal upkeep.
Shenzhen’s secondary water supply systems
One in three people worldwide live without access to clean drinking water. Even major cities with established utilities are projected to fall short of demand for potable water. One of these cities is Shenzhen: China's first free-trade zone and unofficial innovation capital. An ambitious plan specifies molybdenum-containing Type 316 stainless steel distribution systems as a solution to water loss.
Molybdenum: essential for wind turbines
To prevent the worst outcomes of climate change, renewable energy sources like wind and solar must more than triple their share of global power production. While molybdenum plays a role in several green technologies, it is particularly crucial in wind power generation. Therefore, as the demand for wind turbines increases, so will the demand for molybdenum in many of their components.
