Material Production

Material Production

The rapid change and mobility in today’s market conditions increases the demand and expectation for engineering materials. Trial and error in a test environment, both in terms of cost and tight project timelines, prevents companies from developing high-performance materials quickly enough to meet demand. The Computational Materials Engineering® approach bridges this gap and is emerging as a proven methodology for developing new high-performance materials and optimizing existing materials faster and at lower cost than a traditional trial-and-error or experimental approach.


ONATUS Foresight Technologies, using Computational Materials Engineering numerical modeling software, intensively produces projects, establishes software infrastructures and develops solutions within the scope of consultancy in line with the basic needs and future targets of our country, for metallic material producer companies and their customers in the defense & automotive field.


All qualified steel producers in our country; Erdemir, İsdemir, Çolakoğlu, Çemtaş, Asil Çelik…can be listed as the main industrial companies for which ONATUS provides solutions.


Onatus is intensively involved in the manufacturing and design processes of many metals such as titanium, aluminum, magnesium, nickel-based super alloys planned to be commissioned for defense industry projects.

Thermo-Calc


Thermo-Calc has been the most widely used and powerful software package for thermodynamic calculations in the world for the last 30 years. Thermo-Calc is used extensively in the following process calculations:

• Stable and metastable phase calculations
• The size of the phases and the percentage distribution of the elements they contain
• Thermochemical calculations such as enthalpy, heat capacity and activation energy
• Transformation temperatures such as lycudus and solidus
• Main process parameters affecting phase transformations
• Creation of single, double, triple and multiple phase diagrams
• Solidification calculations according to Scheil-Gulliver model
• Calculation of thermodynamic properties of chemical reactions

Dictra


DICTRA is a software solution developed by Thermo-Calc for precise diffusion controlled calculations of multicomponent alloys. DICTRA calculations are based on solving the diffusion equations of alloys by numerical methods. Some basic calculations that can be done with the help of DICTRA can be listed as follows:

• Microsegregations during solidification
• Homogenization of alloys
• Growth/dissolution reactions: carbides, nitrides and intermetallic phases
• Precipitate phase formations
• Interdiffusion calculations, for example in coating systems
• Austenite – ferrite transformations in steels
• Carburizing, nitriding and carbonitriding reactions of alloys and steels at elevated temperatures
• Thermo-dynamic reactions occurring in successive welding and heat treatments
• Sintering reactions of cemented carbides

TC Prisma


TC-PRISMA is a software solution developed by Thermo-Calc for the analysis of nucleation, grain growth, dissolution and grain coarsening behavior of multi-component and multi-phase structures under user-specified heat treatment conditions using Langer-Schwartz theory and Kampmann-Wagner numerical modeling approaches.


TC-PRISMA significantly increases its current analysis and modeling capabilities when used in conjunction with the Thermo-Calc and DICTRA software solutions, also developed by Thermo-Calc.


The following analysis and simulation studies can be performed using TC-PRISMA

• Simultaneous grain formation, grain growth/dissolution and sediment coarsening calculations
• Temperature dependent particle distribution in the analyzed system
• Average particle radius and number density
• Volume fraction and particle composition
• Nucleation and coarsening rates
• Time – Temperature – Precipitation (TTP) diagrams
• Interface energy of multicomponent structures

Thercast NxT


Thercast is our simulation software solution that enables the identification of possible casting defects before the casting process by creating numerical models of ingot, continuous casting and die casting methods used in metallic material production processes in a computer environment and enabling the necessary improvement activities to be commissioned. Most of the metallic material manufacturers in the world and in our country use Thercast software in order to observe capillary cracks, bleeding, segregations, casting voids that may occur on the line before the processes.


Thercast offers its users integrated simulation with its user-friendly interface and Forge NxT software integration. By linking rolling and forging processes with casting processes, it makes it possible to develop more realistic and accurate approaches. In other words, if the cast part is continued with rolling or forging, data can be exchanged between these two processes and then fast and practical solutions can be developed.
