Effectively Sourcing Foundry Partners on AFS Supplier Marketplace

Learn how to make sourcing decisions easier and more efficiently with the AFS Supplier Marketplace, an interactive directory of foundry supplier partners. This webinar will review the features of this online resource that allows foundry... more

The effect of cooling rate on the microstructure and physical properties of hypereutectic Al-Ce alloys

The present study investigated the effect of cooling rate on the solidification of hypereutectic Al-Ce alloys, where varying cooling rates were obtained using a step casting mold. The thinner section sizes led to higher cooling rates, leading to a... more

Remanufacturing of Military Castings on the Battlefield

The global dominance of our US military depends on a reliable supply chain of replacement parts for our troops abroad.  Steel castings are prolific in all areas of the military and play a vital role in national defense.  Unfortunately, interruptions... more

Effects of Casting Defects on Distortion in High Intensity Quench Systems’

This is a continuation of previous study of low-alloy steel quench hardening using forced convection bath (FCB) and intensive quench (IQ) systems. Work has been done to characterize the contributions of surface defects, carbon content, and... more

Analysis of Next Generation Bearing Steels

One of the largest obstacles for single row tapered roller bearings on wind turbines is the yield strength of its interior parts. Several studies have found improving strength levels by making expensive alloy additions or unconventional thermal... more

Loss of Kinetic Zone Pressure Causes Mold Wall Collapse During Filling Across a Glue Joint in Lost Foam Casting

Mold wall collapse in the lost foam casting process has been largely associated with poor sand compaction where pattern design and glue line placement has been overlooked. In this paper, the design and location of glue joints is studied to determine... more

Monitoring Curing Effectiveness of Chemically Bonded Sand Molds using Embedded Sensors

The phenolic urethane reaction causes byproducts to be emitted from molds as they cure. These emissions are thought to be linked to the physical property development of chemically bonded sand molds. The amount of emissions generated are typically... more

Fast Moisture and VOC Test

The percent Moisture Content (MC) and Percent Volatile Organic Compounds (VOC) and Loss-on-Ignition (LOI) are standardized testing procedures for the American Foundry Society (AFS). Excess water vapor, gaseous organic solvents, and total organics in... more

3D Printed Sand Molds Using Selective Powder Deposition

Selective powder deposition (SPD) is an additive manufacturing technology developed to produce metal parts. In the process, unbound metal and support powders are deposited in a layer-by-layer fashion to produce the desired geometry. The build... more

Towards a Fully Recycled Aluminum Alloy for Automotive Applications

Aluminum alloys possess excellent mechanical properties and corrosion resistance that make them desirable for applications in the automotive industry. Additionally, aluminum is infinitely recyclable with excellent recovery rates. However, recycling... more
