Metal Etched Blades and Wave

A metal etching can enhance the blade or spine of a knife. The designs are limited by your artistic ability. Check out the examples of metal etched flames and waves.

Etch-Omatic: An Easy Marking System

You can mark anything metal, including tools, instruments, metal parts and equipment. The Etch-O-Matic can be used in many ways. ETCH-O-MATIC is easy to use.

Anyone in your organization can become an expert in just a few minutes. The very easy marking system to learn is called Etch-O-Matic. ETCH-O-MATIC is the least EXPENSIVE method on the market today, and it is the fastest way to make permanent marks on metal.

Cut out your design

3. Cut out your design. An X-Acto knife is good for this. The parts that are covered by vinyl will not change color, but will become lighter due to the interaction with the acid.

The Shapes of Anvil

If you're new to blacksmithing, you might be wondering about the shapes that make up anvil. The physical design on anvils has been refined.

Brushing the Damascuses

You can use a toothbrush to make sure the acid is penetrating, but brushing is the best way to make sure you get an even etch. If you missed oil or grease in the Damascus, brush it in the acid with an old toothbrush to help remove it and to brush away the dissolving material as the acid does its job.

The influence of the composition on martensite formation in austenitic stainless steels

H1 is austenitic steel. The development of sennatic steels was done by German metallurgists in the early 20th century. They worked on 18% and 8% Ni steels which are similar to common austenitic steels.

The austenite phase field is much larger and the delta ferrite phase field is much smaller after the 8% Ni addition. The steel can be heated to austenite before rapid cooling to retain austenite at room temperature. Depending on the composition of the steel, different austeniticstainless steels are more or less susceptible to transforming to martensite during deformation.

Composition has different effects on the start temperature. The temperature at which 50% martensite forms with 30% strain is predicted by an equation. The strain can be increased with a higher MD30

The nickel is reduced to 7% relative to 302 and 304, which helps promote martensite formation. The steels have a reduced amount of chromium. It reduces the resistance tocorrosion but it also promotes the formation of martensite.

During the slow solidification of molten steel segregation, Delta ferrite is sometimes present in austenitic stainless steels. The elements will form a diffuse area with more or less of a given element. The ferrite is stable when it is separated into certain regions.
