help you fix your problem Well, the problem its because u not encapsulate radio in a object. To work your code need do something like this:
My HTML:
code :
<md-radio-group ng-model="effectSelected.selected" class="effect-radio-group">
  <md-radio-button class="effect-btn" ng-repeat="effect in effects" ng-value="effect.value">{{effect.name}}</md-radio-button>
</md-radio-group>

<md-button ng-click="checkSelection()">Evaluate</md-button>
   $scope.effects = [{'name':'None', 'value': 'one'},{'name':'Maybe', 'value': 'two'},{'name':'Yes', 'value': 'three'}];
   $scope.effectSelected = { selected:'one'}
   $scope.checkSelection() = function () {
       console.log($scope.effectSelected.selected);
   }

I wish this help you If you look closer to the elements created by md-radio-group you will notice this:
code :
<label class="mat-radio-label" for="md-radio-2-input">
    <div class="mat-radio-container">
        <div class="mat-radio-outer-circle"></div>
        <div class="mat-radio-inner-circle"></div>
        <div class="mat-radio-ripple mat-ripple" md-ripple="" ng-reflect-trigger="[object HTMLLabelElement]"
             ng-reflect-centered="true" ng-reflect-disabled="false"></div>
    </div>
    <input class="mat-radio-input cdk-visually-hidden" type="radio" id="md-radio-2-input" name="md-radio-group-0">
    <div class="mat-radio-label-content"><span style="display:none">&nbsp;</span>Option 2</div>
</label>
.mat-radio-label {
    cursor: pointer;
    display: inline-flex;
    align-items: center;
    white-space: nowrap;
    vertical-align: middle;
}

it helps some times You will need the name="your_name" near [(ngModel)], then the checked property will not work but you can do like this.
code :
<form>  
 <mat-radio-group [(ngModel)]="radioOptions" name="radioButtons">
    <mat-radio-button [value]="'TEST1'">TEST1</mat-radio-button>
    <mat-radio-button [value]="'TEST2'">TEST2</mat-radio-button>
</mat-radio-group> </form>

  import { FormsModule } from '@angular/forms';
  export class ConfigurazioneComponent implements OnInit {
     radioOptions: string = 'TEST1'; 
  }

it should still fix some issue The code you shared to dynamically render and manipulate material radio button group values is correct. The issue is most likely in how/where this._choice.animal is being evaluated. It that value is retrieved via something like HttpClient get(), make sure to evaluate this._choice.animal inside subscribe() or then() if it's a Promise:
code :
import { Component } from '@angular/core';

@Component({
  selector: 'radio-overview-example',
  templateUrl: 'radio-overview-example.html',
  styleUrls: ['radio-overview-example.css'],
})
export class RadioOverviewExample {
  public animalOptions: any = [
    { label: 'cat', value: '1', checked: true },
    { label: 'dog', value: '2', checked: false }
  ];

  public _choice: any;

  ngOnInit() {
    this.getSomeApiValue().subscribe(result => {
      this._choice.animal = result;

      if (this._choice.animal === 'cat') {
        this.animalOptions[0].checked = false;
        this.animalOptions[1].checked = true;
      }
    });
  }
}

I wish this helpful for you You should be using ng-container instead of ng-template and expressType instead of te to compare to the Component n value.
Try this:
code :
<mat-radio-group [(ngModel)]="expressType">
  <mat-radio-button class="example-radio-button" *ngFor="let te of typeExpress" [value]="te">
    {{ te }}
  </mat-radio-button>
</mat-radio-group>

<ng-container *ngIf="expressType === 'Component 1'">
  <app-component1></app-component1>
</ng-container>
<ng-container *ngIf="expressType === 'Component 2'">
  <app-component2></app-component2>
</ng-container>
<ng-container *ngIf="expressType === 'Component 3'">
  <app-component3></app-component3>
</ng-container>

<h1>Or with ng-template</h1>

<ng-template [ngIf]="expressType === 'Component 1'">
  <app-component1></app-component1>
</ng-template>
<ng-template [ngIf]="expressType === 'Component 2'">
  <app-component2></app-component2>
</ng-template>
<ng-template [ngIf]="expressType === 'Component 3'">
  <app-component3></app-component3>
</ng-template>
