HIGH STRENGTH GRADIENT STEELS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18076693 titled 'HIGH STRENGTH GRADIENT STEELS

The abstract describes a gradient steel with multiple layers, each containing different ferrite phase volumes.

• The gradient steel consists of a first layer with a first ferrite phase volume.
• A second layer near the first surface of the first layer and a third layer near the second surface of the first layer contain a second ferrite phase volume greater than the first ferrite phase volume.
• Additional layers, such as a fourth layer near the second layer and a fifth layer near the third layer, may contain even higher ferrite phase volumes.
• The gradient steel may also include sixth and seventh layers with further increased ferrite phase volumes.

Potential Applications: - This gradient steel could be used in structural applications where varying strength and hardness are required. - It may find applications in the automotive industry for components that need to withstand different levels of stress.

Problems Solved: - Provides a material with a gradient of ferrite phase volumes, offering tailored mechanical properties.

Benefits: - Enhanced strength and hardness in specific areas of a component. - Improved performance under varying stress conditions.

Commercial Applications: - Structural components in aerospace and automotive industries. - Manufacturing of tools and equipment requiring specific mechanical properties.

Prior Art: - Prior research on gradient materials and their applications in engineering and manufacturing.

Frequently Updated Research: - Ongoing studies on the optimization of ferrite phase volumes in gradient steels for improved performance.

Questions about Gradient Steel: 1. How does the gradient steel's composition affect its mechanical properties? 2. What are the potential cost implications of using gradient steel in industrial applications?

Original Abstract Submitted

A gradient steel includes a first layer, a second layer near a first surface of the first layer, and a third layer near a second surface of the first layer. The first layer includes a first ferrite phase volume. The second and third layers include a second ferrite phase volume greater than the first ferrite phase volume. The gradient steel may also include a fourth layer near the second layer and a fifth layer near the third layer. The fourth and fifth layers may each include a third ferrite phase volume greater than the second ferrite phase volume. The gradient steel may also include a sixth layer near the fourth layer and a seventh layer near the fifth layer. The sixth and seventh layers may each include a fourth ferrite phase volume greater than the third ferrite phase volume.
